Although often the distinction between non-strategic and strategic philanthropy is adopted, some authors choose to classify philanthropy based on business motivations. Porter & Kramer, for example, identify three categories of philanthropy: communal obligation philanthropy, goodwill building philanthropy, and strategic giving philanthropy (Porter and Kramer 2002). Porter & Kramer define communal obligation philanthropy as “support of civic welfare, and educational organizations, motivated by the company’s desire to be a good citizen” (Porter and Kramer 2002). This is distinguished from their view of good will building philanthropy which they define as “contributions to support causes favored by employees, customers, or community leaders, often necessitated by the quid pro quo of business and the desire to improve the company’s relationships” (Porter and Kramer 2002). Finally, Porter and Kramer define strategic giving philanthropy as “philanthropy focused on enhancing competitive context” (Porter and Kramer 2002). These three categories are distinguished by the motivation of the business in their philanthropic efforts. That is, what motivates the business to give determines which category the philanthropy will fall under.
